Non-Intrusive Traffic Monitoring System (NTMS)

Description

The Spectra Research NTMS is a portable, accurate and non-intrusive sensor for monitoring multi-lane traffic from the side of the highway. The NTMS consists of two identical laser radar (LADAR) channels (separated by 1.0 feet) contained in an enclosure which serves as an optical platform and protects it from the elements. The NTMS sensor emulates two road tubes or tape switches per lane for 1 to 4 lanes of traffic. The NTMS interfaces to the auxiliary port (tape switch input) of an existing traffic monitoring device, such as the Diamond Phoenix or equivalent device. The sensor is designed to operate on the road shoulder, 12-15 feet from the nearest lane of traffic. The sensor is non-intrusive and eliminates the need to install road tubes, loops or tape switches within traffic lanes, minimizing traffic delays and hazard to traffic engineers.

Status

S*R currently has two prototype units in ongoing field tests for the purposes of demonstrating the technology and developing comparative data.
A patent application is in progress for the dual-beam laser sensor incorporated in the NTMS design.

Profiler


Description

The Spectra Research Laser Pavement Profiler is a non-contact optical measurement instrument which measures the distance to the pavement surface with 0.0012 inch resolution over a measurement range of 5 inches and at a rate of 64,000 samples per second. It is suitable for acquiring both gross pavement profile and surface texture information from a vehicle moving at speeds up to 60 MPH.

Status

Spectra Research is actively seeking partnerships with companies, government agencies, universities and individuals with interest in using or producing S*R laser pavement profiler technology.
